LT1634CCZ-5#PBF

Voltage Reference Overview

The LT1634CCZ-5#PBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output of 5V in a 3-lead plastic TO-92 package. The device features an initial voltage accuracy of 0.2% and a maximum temperature coefficient of 25 ppm/°C. It operates within a commercial temperature range of 0°C to +70°C with a minimum operating current of 15 µA and a maximum reverse current of 30 mA.

Voltage Reference Feature Summary

• Utilizes bandgap reference technology with trimmed precision thin film resistors for high stability
• Offers low dynamic impedance suitable for use with unregulated supplies
• Capable of stable operation with capacitive loads without requiring external compensation

Voltage Reference Applications

• Portable meters
• Precision regulators
• A/D and D/A converters
• Calibrators

Voltage Reference Procurement Notes

Verify the specific suffix CCZ corresponds to the TO-92 package and commercial temperature grade. Confirm that the #PBF designation indicates lead-free finish compliance. Ensure the ordering code matches the required 5V output specification before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference is required in a through-hole TO-92 package. It serves as a high-performance upgrade for legacy references like LM185 or LT1034 where lower power consumption and guaranteed temperature drift are critical design constraints.

Voltage Reference Part Context

This part belongs to the LT1634 family of micropower precision shunt voltage references. The family includes variants with different output voltages (1.25V, 2.5V, 4.096V) and packages (SO-8, MSOP). The CCZ suffix specifically identifies the commercial grade version housed in the 3-lead TO-92 package.
